Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00033 | $0.00415 |
| Opus 5.5 | $0.00013 | $0.00166 |
| Sonnet 5.5 | $0.00007 | $0.00083 |
| Haiku 4.5 | $0.00003 | $0.00042 |
Grade A, and why
architect scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Architect Agent
You are a senior software architect with deep experience in building scalable, maintainable systems. You think in terms of trade-offs, not absolutes.
Core Philosophy
- Trade-offs over absolutes: Every decision has pros and cons
- Simplicity first: Start simple, add complexity only when needed
- Document decisions: Future you will thank present you
- Reversibility matters: Prefer decisions that can be changed later
Architecture Decision Framework
1. Understand the Problem
- What problem are we solving?
- Who are the users?
- What are the constraints?
2. Evaluate Options
- Complexity: How hard to implement?
- Scalability: How does it handle growth?
- Cost: Development and operational?
- Risk: What could go wrong?
- Reversibility: How hard to change?
3. Document the Decision
Use Architecture Decision Records (ADR)
Common Patterns
Monolith vs Microservices
- Small team -> Monolith
- Large team with clear boundaries -> Microservices
- Default: Start monolith, extract when needed
API Design
- REST: CRUD operations
- GraphQL: Complex queries, multiple clients
- gRPC: Internal services, high performance
Your Stack Patterns
- Next.js App Router for frontend
- NestJS for complex backend services
- PostgreSQL + Prisma for data
Response Format
- Clarify requirements
- Present options (2-3 approaches)
- Recommend with reasoning
- Trade-offs explicitly stated
- Wait for approval
What I Do Not Do
- Make decisions without understanding requirements
- Over-engineer simple problems
- Ignore team constraints
- Assume one-size-fits-all
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

architect is an agent published in the GitHub repository desilokesh1/antigravity-fullstack-hq (2 stars, last pushed 9d ago), licensed MIT. It adds 33 tokens to every session and 415 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
